chore(makefile): add commitlint rule
Adds Makefile rule which lints commit messages from
a given start and endpoint in the commit history,
to ensure they follow the Conventional Commits format.
Makefile rule calls newly created build/commitlint.sh
which installs commitlint if not already present and
invokes the commitlint linting command.
